# GestureStroke

`public class GestureStroke`
`extends Object` ``

java.lang.Object
↳ | android.gesture.GestureStroke

A gesture stroke started on a touch down and ended on a touch up. A stroke consists of a sequence of timed points. One or multiple strokes form a gesture.

## Summary

### Fields
`public final RectF` | `boundingBox`
`public final float` | `length`
`public final float[]` | `points`

### Public constructors
`GestureStroke(ArrayList<GesturePoint> points)` A constructor that constructs a gesture stroke from a list of gesture points.

### Public methods
`void` | `clearPath()` Invalidates the cached path that is used to render the stroke.
`Object` | `clone()` Creates and returns a copy of this object.
`OrientedBoundingBox` | `computeOrientedBoundingBox()` Computes an oriented bounding box of the stroke.
`Path` | `getPath()`
`Path` | `toPath(float width, float height, int numSample)` Converts the stroke to a Path of a given number of points.

### Inherited methods
From class `java.lang.Object`
`Object` | `clone()` Creates and returns a copy of this object.
`boolean` | `equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void` | `finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>` | `getClass()` Returns the runtime class of this `Object`.
`int` | `hashCode()` Returns a hash code value for the object.
`final void` | `notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void` | `notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String` | `toString()` Returns a string representation of the object.
`final void` | `wait(long timeout, int nanos)` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
`final void` | `wait(long timeout)` Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.
`final void` | `wait()` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.

## Fields

### boundingBox

    public final RectF boundingBox

### length

    public final float length

### points

    public final float[] points

## Public constructors

### GestureStroke

    public GestureStroke (ArrayList<GesturePoint> points)

A constructor that constructs a gesture stroke from a list of gesture points.

## Public methods

### clearPath

    public void clearPath ()

Invalidates the cached path that is used to render the stroke.

### clone

    public Object clone ()

Creates and returns a copy of this object. The precise meaning of "copy" may depend on the class of the object. The general intent is that, for any object `x`, the expression:

>      x.clone() != x

will be true, and that the expression:

>      x.clone().getClass() == x.getClass()

will be `true`, but these are not absolute requirements. While it is typically the case that:

>      x.clone().equals(x)

will be `true`, this is not an absolute requirement.

By convention, the returned object should be obtained by calling `super.clone`. If a class and all of its superclasses (except `Object`) obey this convention, it will be the case that `x.clone().getClass() == x.getClass()`.

By convention, the object returned by this method should be independent of this object (which is being cloned). To achieve this independence, it may be necessary to modify one or more fields of the object returned by `super.clone` before returning it. Typically, this means copying any mutable objects that comprise the internal "deep structure" of the object being cloned and replacing the references to these objects with references to the copies. If a class contains only primitive fields or references to immutable objects, then it is usually the case that no fields in the object returned by `super.clone` need to be modified.

The method `clone` for class `Object` performs a specific cloning operation. First, if the class of this object does not implement the interface `Cloneable`, then a `CloneNotSupportedException` is thrown. Note that all arrays are considered to implement the interface `Cloneable` and that the return type of the `clone` method of an array type `T[]` is `T[]` where T is any reference or primitive type. Otherwise, this method creates a new instance of the class of this object and initializes all its fields with exactly the contents of the corresponding fields of this object, as if by assignment; the contents of the fields are not themselves cloned. Thus, this method performs a "shallow copy" of this object, not a "deep copy" operation.

The class `Object` does not itself implement the interface `Cloneable`, so calling the `clone` method on an object whose class is `Object` will result in throwing an exception at run time.

Returns
`Object` | a clone of this instance.

### computeOrientedBoundingBox

    public OrientedBoundingBox computeOrientedBoundingBox ()

Computes an oriented bounding box of the stroke.

Returns
`OrientedBoundingBox` | OrientedBoundingBox

### getPath

    public Path getPath ()

Returns
`Path` |

### toPath

    public Path toPath (float width,
                    float height,
                    int numSample)

Converts the stroke to a Path of a given number of points.

Parameters
`width` | `float`: the width of the bounding box of the target path
`height` | `float`: the height of the bounding box of the target path
`numSample` | `int`: the number of points needed

Returns
`Path` | the path
